Kapitza-resistance-like exciton dynamics in atomically flat MoSe-WSe lateral heterojunction
Hassan Lamsaadi, Dorian Beret, Ioannis Paradisanos +13
Being able to control the neutral excitonic flux is a mandatory step for the development of future room-temperature two-dimensional excitonic devices. Semiconducting Monolayer Tran…
Hyper-doped silicon nanoantennas and metasurfaces for tunable infrared plasmonics
Jean-Marie Poumirol, Clément Majorel, Nicolas Chery +11
We present the experimental realization of ordered arrays of hyper-doped silicon nanodisks, which exhibit a localized surface plasmon resonance. The plasmon is widely tunable in a…
Unveiling the optical emission channels of monolayer semiconductors coupled to silicon nanoantennas
Jean-Marie Poumirol, Ioannis Paradisanos, Shivangi Shree +13
Monolayers (MLs) of transition metal dichalcogenides (TMDs) such as WSe2 and MoSe2 can be placed by dry stamping directly on broadband dielectric resonators, which have the ability…
Enhancement of electric and magnetic dipole transition of rare-earth doped thin films tailored by high-index dielectric nanostructures
Peter R. Wiecha, Clément Majorel, Christian Girard +7
We propose a simple experimental technique to separately map the emission from electric and magnetic dipole transitions close to single dielectric nanostructures, using a few nanom…
Enhanced nonlinear optical response from individual silicon nanowires
Peter R. Wiecha, Arnaud Arbouet, Houssem Kallel +3
We report about the experimental observation and characterization of nonlinear optical properties of individual silicon nanowires of different dimensions. Our results show that the…
Strongly directional scattering from dielectric nanowires
Peter R. Wiecha, Aurélien Cuche, Arnaud Arbouet +8
It has been experimentally demonstrated only recently that a simultaneous excitation of interfering electric and magnetic resonances can lead to uni-directional scattering of visib…
